The lighting was not that bright in that gallery since the room was partially dark it was mostly directly focused on the objects. A bright light was on the statue and on the two-wall text next to the statue as well. In the room a bright light was mostly used to be focus on the objects to show more importance and make it more interesting to look at it.
My hypotheses about its context is that it talks about the human mortality and the importance of the afterlife to the Egyptians based on religion. The statue of Osiris belongs in that gallery because it relates to immortality by using spells and rituals from the book of the dead to be one with the gods. I don’t think that the piece of statue doesn’t belong in that gallery since it all relates to death and life for example, the transformation of any living person as an immortal god in the afterlife and the rebirth.
Some question to have a better understanding of the piece’s context is that why it’s not a surprise to find more objects that are in the form of Osiris in the tomb items. I would want to know what other items were in with this statue. Also, why is the Osiris statue on its own without other figures about this eternal god in the gallery. Another question I would want to know is how Osiris became the lord of the eternity in the first
